A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry, and channel bed particle size distribution the model predicts the flow depth, the mean velocity, and the flow resistance. Energy losses are assumed to result from flow resistance, as well as from local losses generated by the contractions and expansions occurring through the pool and riffle sequence. The model has been verified using laboratory and field data.
